ICL is safe for these sports after the usual recovery period of 4-6 weeks. During the post-operative recovery period, it is important to keep the eyes very clean and avoid contaminating the eyes in places like swimming pool or hot baths.
In general, the risk of trauma in post-ICL eyes such as ball injury or contact sports (e.g. boxing or rugby) is low, but there is a chance that such injuries may predispose to a shift in position of the ICL or even rupture of the small cornea incision.
From my years of performing ICL surgeries, I have certainly never come across such cases in real life. However, these cases have been reported in the scientific literature, albeit very rarely. For those engaging in contact sports, protective gear is highly recommended to guard against eye injury.
Hope this helps!
